Thus, thedriving gear 32 is driven and rotated by thedrive motor 31 to rotate the drivengear 33 which drives thedriving shaft 34 which drives therotation lever 29 to deflect and swing. Thebattery box 36 of thedriving unit 3 contains at least one battery to provide an electric power to thedrive motor 31. Thedriving shaft 34 of thedriving unit 3 is deflected eccentrically from a central portion of the drivengear 33. - In operation, referring to
FIGS. 3-5 with reference toFIGS. 1 and 2 , when thedrive motor 31 is operated, thedriving gear 32 is driven and rotated by thedrive motor 31 to rotate the drivengear 33 which drives thedriving shaft 34 which drives therotation lever 29 which drives thedriving member 28 which pivots about thesupport shaft 261 and drives thetorsion spring 281 which drives thetransmission member 26 which pivots about thesupport shaft 261 and drives the drivingaxles 27 which are moved reciprocally in thelimit slots 211 of thebase 21 and drive the drivenpieces 23 which drive theswinging arm 22 which drives thepivot block 24 which drives thedrawing bracket 25. At this time, thedrawing bracket 25 is fixed by one of thecrossbars 12 of theframe unit 1 and cannot be moved by thepivot block 24, while thepivot block 24 cannot be moved by the swingingarm 22 so that the swingingarm 22 is pivoted horizontally about thepivot block 24. In such a manner, when the swingingarm 22 is pivoted about thepivot block 24, the drivingaxles 27 are moved reciprocally in thelimit slots 211 of the base 21 to move the base 21 as shown inFIG. 4 which drives thebed board 16 which drives the support frames 14 which drive the swingingbrackets 13 which are pivoted relative to thecrossbars 12, so that thebed board 16 is driven by thebase 21 and is rocked through the support frames 14 and the swingingbrackets 13 as shown inFIG. 5 . At the same time, thetop frame 15 is also moved in concert with the support frames 14. Thus, thebed board 16, thetop frame 15, the support frames 14 and the swingingbrackets 13 are rocked reciprocally relative to the bottom frames 11 and thecrossbars 12 by successive operation of thedrive motor 31. - On the contrary, referring to
FIGS. 6 and 7 with reference toFIGS. 1-5 , the rocking bed further comprises at least onelocking hook 40 pivotally connected with one of the support frames 14 and removably locked onto the swingingbrackets 13. In operation, when the lockinghook 40 is locked onto the swingingbrackets 13, the support frames 14 and the swingingbrackets 13 are locked so that thebed board 16 is disposed at a fixed state and cannot be rocked any more. In such a manner, when thedrive motor 31 is operated successively, thedriving gear 32 is driven and rotated by thedrive motor 31 to rotate the drivengear 33 which drives the drivingshaft 34 which drives therotation lever 29 which drives the drivingmember 28 which pivots about thesupport shaft 261 and drives thetorsion spring 281 which drives thetransmission member 26. At the same time, thebase 21 is fixed by thebed board 16 of theframe unit 1 so that thetransmission member 26 is fixed by thebase 21. Thus, when the drivingmember 28 drives thetorsion spring 281 to drive thetransmission member 26, thetorsion spring 281 is compressed between the drivingmember 28 and thetransmission member 26 and cannot drive thetransmission member 26, so that thedrive motor 31 idles to prevent thedrive motor 31 from being worn or broken due to a jam between the drivingmember 28 and thetransmission member 26. - Accordingly, the
bed board 16, thetop frame 15, the support frames 14 and the swingingbrackets 13 are rocked reciprocally relative to the bottom frames 11 and thecrossbars 12 by successive operation of thedrive motor 31 so that the rocking bed is rocked reciprocally without needing a manual work, thereby facilitating a user taking care of babies placed in the rocking bed. - Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
